IMPROVED REGULATOR FOR GAS-BURNERS.

Specification forming part of Letters Patent No. 57,087, dated August 14, 1866.

To all whom it may concern:

Be it known that I, .WILLIAM CLARK, of Boston, in the county of Sufiolk and State of Massachusetts,have invented an Improvement cient to enable those skilled in the art to practiceit.

This invention relates to the improvement of the devices which are frequently introduced into gas-burners near the orifice therein at which the gas escapes and close to which it is burned, between said orifice and the cock by which the supply of gas is admitted to or is shut off from the burner.

This device, usually termed a regulator, has for its objectthe control of the flow of the gas-currentand the reduction of its pressure by wire-drawing it, so termed, through small apertures, and by lessening the momentum of the current.

This invention consists in s'ucha regulating device, so constructed and,arranged that while it is capable of adjustment to increase orldiminish the area of the opening for the flow of the gascurrent, it shall discharge the gas within the burner toward its longitudinal axis, and so that the particles of gas, in their impingement against each other at or near said axis, shall thereby have their momentum lessened, and shall proceed to the escaping-orifice from the burner in the line of the axis thereof as the resultant line of motion produced by the form given to the regulator-passage and the impingement against each other a valve-seat, which the fru'sto-conical valve 1) fits closely on its inclined surface, the diameter of the large end of valve b being smaller than the internal diameter of a, so that when the conical surface of the valve 1) is not in contact with its seat a current of gas can pass the valve.

The piece a, is provided with a central crossbar, 0, in which are cut the screw-threads of a nut fitting the screw-threads formed on the stem at of the valve, so that by turning the valve it is adjusted toward or from its seat, diminishing or increasing the size of the opening through which the gas passes on its way to be burned.

Thegas passing in the annular conical space between the valve 1) and its conical seat is directed thereby toward the apex of the cone of which the valve 1) is the frustum, and the par ticles of gas meeting at that point, having their momentum diminished by their impact against changed thereby, proceed to escape from the orifice in thetip 6.

Practical experiments have proved to me that a current of gas directed toward the burning-orifice by and through an inclined annular passage produces a thinner and better shaped flamethan will any other form of regulator in connection with the same tip, and that a perceptible gain in the amount of light produced from the consumption of a given quantity of gas is thereby obtained.

The pin f in the end of the valve-spindle d serves to prevent accidental loss of the valve 12, and also acts as a handle by which the valve is easily turned, and as an index by which to observe the number of turns or the fraction of a turn given to the valve.
